I just had trouble with the 36mm pressure seals in the Centric kits and a few others around here have had similar problem. The 40 mm seals worked without a problem though. I ended up having to buy 4 of the 36mm seals that were real from Brembo. They were ~$15 a seal versus $15 a kit for the Centric parts, but oh well, you need brakes!

Hopefully this saves someone else problems down the road.
